[Note6] The performance of the backlight, for example life time or brightness, is much influenced
[Note7] It is required to have the inverter designed so that to allow the impedance deviation of the two CCFT lamps
[Note8] Under the environment of 10lx or less, miss-lighting delay may occur.
8. Timing Characteristics of input signals
8-2. Horizontal display position
8-3. Vertical display position
8-1. Timing characteristics
Timing diagrams of input signal are shown in Fig.2.
[Note] In case of lower frequency, the deterioration of display quality, flicker etc.,may be occurred.
The horizontal display position is determined by ENAB signal and the input data corresponding to the
rising edge of ENAB signal is displayed at the left end of the active area.
[Note] When ENAB is fixed "Low", the display starts from the data of C88(clock) as shown in Fig.2.
The vertical display position, TVs is fixed “23” (line).

Recommended inverter is “CXA-0454 (TDK)”.
(“CXA-P1212B-WJL(TDK)” is also recommended under general temperature condition.)
by the characteristics of the DC-AC inverter for the lamp. When you design or order the inverter,
please make sure that a poor lighting caused by the mismatch of the backlight and the inverter
(miss-lighting,flicker, etc.) never occur. when you confirm it, the module should be operated in the same
condition as it is installed in your instrument.
Be sure to use a back light power supply with the safety protection circuit such as the detection circuit
for the excess voltage, excess current and or electric discharge waveform.
Be sure to use the detect circuit by which one side of the CCFT lamps can be controlled independently.
Otherwise, when one side of the CCFT is open, the excess current may possibly be applied to the other
side of the lamp.
